Dear All,
I just installed octave and run an examples in http://www.gnu.org/software/octave/doc/interpreter/Simple-Examples.html#Simple-Examples
After invoke this command:
octave:1> function xdot = f (x, t);
> r = 1.4;
> k = 1.4;
> a = 1.5;
> b = 0.16;
> c = 0.9;
> d = 0.8;
> xdot(1) = r*x(1)*(1 - x(1)/k) - a*x(1)*x(2)/(1 + b*x(1));
> xdot(2) = c*a*x(1)*x(2)/(1 + b*x(1)) - d*x(2);
> endfunction
octave:2> x0 = [1; 2];
octave:3> t = linspace (0, 50, 200)';
octave:4> x = lsode ("f", x0, t);
octave:5> plot (t, x)
octave:6> Expected X11 driver: /usr/lib/gnuplot/gnuplot_x11
Exec failed: No such file or directory
See 'help x11' for more details
My Question:Regards,
- Why there's no integration result?
- Why can't I get the plot of the function?
